how is the following written with only one exponent?
a^3 . a^5
Answer:
The expression 103 is called the exponential expression. ... The exponent applies only to the number that it is next to. ... If −3 is to be the base, it must be written as (−3)4, which means −3 • −3 • −3 ... From row 1 to row 2, the exponential form goes from 105 to 104. ... Following the pattern, you see that 100 is equal to 1.

A line has a slope of 2 and a y-intercept of 9, what is the equation of the line
Answer:
y=2x+9
Step-by-step explanation:
Slope intercept form is y=mx+b
m is the slope (2)
b is the y-intercept (9)
Plug the slope and intercept you were given in and you get the equation of the line in slope intercept form
y=2x+9

HI WHAT IS 7/6 OF 456327=
PLEEEEAAASE HEEEELLLP ME!!!!!!!!
Answer:
532381.5
Step-by-step explanation:
456327 divided by 6 to get 1/6 = 76054.5
76054.5 x 7 to get 7/6 = 532381.5
or 456327 (6/6) + 76054.5 (1/6) =532381.5

The area of a circle is 16.71cm2.
Find the length of the radius rounded to 2 DP.
Answer:
Radius = 2.31 cm
Step-by-step explanation:
Area of circle = 16.71 square centimeters
[tex]\pi r^2 = 16.71 \\3.14r^2=16.71\\r^2=\frac{16.71}{3.14}\\r^2=5.32\\\sqrt{r^2}=\sqrt{5.32}\\r=2.306[/tex]
Radius of circle = 2.31 centimeter
-20t>-80 what is t and how do you graph it on a nuberline
Answer:
Step-by-step explanation:
Divide both sides by -20. If you divide by a negative, you have to switch the inequality sign. So now you have this for t:
t < 4
Draw a circle around 4 on a number line, but do not shade it in. Then everything below 4 is the right answer for the value of t.

PLEASE HELP ME ON THIS THE ANSWERS ARE 1/3 cm/s, 1/2 cm/s, 2/3 cm/s, and 3/2 cm/s
Answer: 3/2 cm per second
========================================================
Explanation:
We could compute the slope of this line to get the answer, or we could simply compute y/x. This shortcut only works because the line goes through the origin. If the line didn't go through the origin, then we would have to use the slope formula.
The unit rate is y/x = 9/6 = 3/2 cm per second. I used the point (9,6) to compute the unit rate.
We can think of the fraction 3/2 as 1.5, so the unit rate is equivalent to 1.5 cm/sec.

Work out the area of a rectangle with base, b = 20mm and perimeter, P = 42mm.
Answer:
20mm
Step-by-step explanation:
base=20mm
base x 2 because there are two long lines
20 x 2 = 40
42-40=2
amount needed on either side to balance
height=1mm
20 x 1 = 20mm
area = 20mm
Answer:
Let the length of the rectangle be 'l'
We have,
Perimeter of rectangle, P = 42mm.
[tex]or, 2(l+b) = 42\\or, l +b = \frac{42}{2} = 21\\or, l + 20 = 21\\or, l = 1mm\\[/tex]
Area of rectangle = [tex]lb = 1(20) = 20mm^{2}[/tex]

Step-by-step explanation:
Some teenagers collected trash for a beach cleanup. The data for the number of pounds of trash collected by each teenager are shown below. 26, 26, 21, 22, 20, 25, 35 What is the standard deviation of the data? 0 pounds 4.66 pounds 5.03 pounds 25.33 pounds
Answer:
4.66
Step-by-step explanation:
We are given the following data
26, 26, 21, 22, 20, 25, 35
Step 1
We find the Mean
Mean = 26+ 26+ 21+ 22+20+25+ 35/7
= 175/7
= 25
Step 2
We find the Standard Deviation
The formula for Standard deviation that we would use is the Population Standard deviation, this is because the data given above is the data of the number of pounds of trash collected by each teenager
= √(x - Mean)²/n
= √(26 - 25)²+( 26 - 25)²+ (21 - 25)²+ (22 - 25)² +(20 - 25)²+(25 - 25)²+ (35 - 25)²/7
= √152/7
= √21.7142857
= 4.65985898
Approximately = 4.66
Answer:
5.03 Pounds (C)

The person above me is right, but you gotta solve for sample data; not population.
!This is for standard deviation!

evaluate 11.5x + 10.7y when x = 3 and y = 4
Answer: 77.3
Step-by-step explanation:
11.5(3)+10.7(4)
11.5 times 3 equals 34.5
and 10.7 times 4 equals 42.8
34.5 plus 42.8 equals 77.3
Answer:
77.3 (see below)
Step-by-step explanation:
To solve, plug in the values given into the expression given and simplify:
11.5x + 10.7y
11.5 (3) + 10.7 (4)
34.5 + 42.8
77.3
